Having updated the BIOS of my Dell Inspiron 510m to the latest version A11, there's still no possibility to set the video memory.
What I noticed though, is the following: The BIOS knows an option 'Video Expansion' which enables/disables the scaling of a lower resolution to a higher, native LCD resolution. The native resolution is 1400x1050 (whence I need tu use the 915resolution- patch). The usplash complains about not being able to set the resolution to 1024x786 nor 800x600 and is running with 640x480 (the splash-screen not being centered very well, if the the scaling is enabled). I disabled this scaling in the BIOS. The boot-splash still runs with 640x480, but is centerd nicely. After login (gnome is running with 1400x1050), when I switch to the tty-consoles (Crtl-Alt-F1) the screen still isn't scaled. Switching back (Crtl-Alt-F7) the mouse-pointer has disappeared. Switching back to tty1 (Crtl-Alt-F1) now the screen is scaled (despite of the BIOS-setting)! (the same true for the splash-screen during shutdown). I presume that this scaling begins already with the switching to Crtl-Alt-F7 (the same with resume after suspend). Could it be possible that the mouse-pointer (which is a hardware-cursor) inherits this scaling of the tty-consoles and due to this cannot be displayed any more together with the graphical surface which is not being scaled? -- mouse pointer disappears after switch to console or resuming from sleep https://launchpad.net/bugs/67196 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
